Abstract
Technologies for filtering network packets on ingress include a network interface controller (NIC) to retrieve classification filters based on packet classification identifying information of a network packet received by the NIC, wherein each of the classification filters is usable to identify rules for identifying any operations to be performed on at least a portion of the received network packet. The NIC is further configured to compare the first classification filter to the packet classification identifying information to determine whether the determined packet classification identifying information meets criteria of the first classification filter. Additionally, the NIC is configured to associate a classification filter identifier of the first classification filter with the received network packet and send the received network packet and the classification filter identifier of the first classification filter to a processor of an apparatus associated with the NIC. Other embodiments are described herein.
